Abstract
A packet loss reduction system. In particular implementations, a method includes responsive to indications of roaming intent of a wireless client relative to currently associated wireless access point, determining if a traffic stream associated with the wireless client is to be proactively buffered by one or more potential wireless access points; conditionally transmitting a command to the one or more potential wireless access points to cause the potential wireless access points to set up resources to proactively buffer packets of the traffic stream; duplicating received packets of the traffic stream destined for the wireless client; and transmitting the duplicate packets to the potential wireless access points for storage in a proactive stream buffer.
